As Simon said, some countries have protectionist policies for various reasons but almost every actual economist I have listened to has said Trumps tariff chart is mostly fantasy.
I read that the weighted average of tariffs the EU applies to US goods is 1%.
It seems obvious there is something bigger going here. There are theories that Trump wants to divide the world into 3 between US/ Russia/ China - with each administering their own region. That would mean Canada is to the US as Ukraine is to Russia. Trump has described Canada's border as fictional.
